TCI6638K2K: Ethrenet init code between U-Boot and PDK

Part Number:TCI6638K2K

Hi,

I've found that initialization codes for 1G/10G Ethernet look different between Keystone U-Boot and PDK.

Especially, SGMII and SERDES initialization have different reset sequence between U-Boot and PDK code.

I downloaded Keystone U-Boot from "git.ti.com/.../u-boot".

Can I use Keystone U-Boot without any fix? How about PDK code?

I have to use both of them, U-Boot for bootloader and PDK for OS.
